The RCX2520Q Selectable XO combines small size and low RMS phase jitter with the ability to select output frequency from one of four factory‐configured values. By combining multiple oscillator specifications into one part, the RCX2520Q can be used to reduce unique part count and provide built-in upgrade paths.

FEATUREs
◾ Up to four frequency selections in one part
◾ LVCMOS, LVPECL, or LVDS output options
◾ 1.0ps RMS phase jitter (12kHz to 20MHz)
◾ Wide frequency range
◾ Fast sample turn around

APPLICATIONs
◾ Ethernet (10G/40G/100G)
◾ Communications
◾ Base Stations
◾ DSL/ADSL
◾ PON/FTTH
